Already fly by wire aircraft are much simpler to operate
Well they are, and they are not.
When all is going well, they are definately easier.
However when it goes pear shaped the complexities of the auto flight system, the multiple interelations between complex modes, and the design of keeping the pilot one stage removed from the "loop" results in a reduction in SA. It demands a need for modern pilots to fully understand poorly designed software, and badly designed interfaces.
Glass cockpits, and FBW have created more problems than they have solved. One step forward, two steps back.
IMHO.
